Abstract
Abstract A color filter is laminated via a resin layer on an electroluminescence device. The resin layer includes silicone resin as its main ingredient while having a thickness of 2 to 100 μm. Thereby, possible color dislocation and reduction of the angle of visibility attributed to the gap between the electroluminescence device and the color filter are prevented. Furthermore, possible damage, dielectric breakdown, pixel dropout, and line defect due to the contact between the electroluminescence device and the color filter are reduced. A surface of the resin layer is changed in condition to make the resin layer have a lipophilic property to facilitate application of a material of the color filter thereto.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
73 words
A color film electroluminescence panel, comprising: an electroluminescence device; buffer means, provided on the electroluminescence device, including silicon resin as a main ingredient thereof and having a thickness of at least 2 μm for reducing the possibility of dielectric breakdown of the color film electroluminescence panel by creating a buffer between the electroluminescence device and a color filter; and the color filter, laminated via the dielectric breakdown reduction means onto the electroluminescence device.
Claim 2
Dependent Claim
73 words
A color film electroluminescence panel, comprising: an electroluminescence device; buffer means, provided on the electroluminescence device, including silicon resin as a main ingredient thereof and having a thickness of at least 2 μm for reducing the possibility of dielectric breakdown of the color film electroluminescence panel by creating a buffer between the electroluminescence device and a color filter; and the color filter, laminated via the dielectric breakdown reduction means onto the electroluminescence device.
Claim 3
Dependent Claim
38 words
A color film electroluminescence panel as claimed in claim 1, wherein the buffer means includes a resin layer, which is comprised of a laminate film formed by providing a silicon-modified epoxy resin layer on a silicon resin layer.
Claim 4
Dependent Claim
45 words
A color film electroluminescence panel as claimed in claim 1, wherein the buffer means includes a resin layer, which is subjected to a process to change its surface from a hydrophilic property to a lipophilic property to thereby enable stable formation of the color filter.
Claim 5
Dependent Claim
60 words
A color film electroluminescence panel as claimed in claim 1, wherein the buffer means includes a resin layer, which has a constant layer thickness in the range of 2 μm to 100 μm to thereby ensure existence of a constant gap between the electroluminescence device and the color filter, to prevent color dislocation and to reduce the angle of visibility.
Claim 6
Dependent Claim
60 words
A color film electroluminescence panel as claimed in claim 2, wherein the buffer means includes a resin layer, which has a constant layer thickness in the range of 2 μm to 100 μm to thereby ensure existence of a constant gap between the electroluminescence device and the color filter, to prevent color dislocation and to reduce the angle of visibility.
Claim 7
Dependent Claim
60 words
A color film electroluminescence panel as claimed in claim 3, wherein the buffer means includes a resin layer, which has a constant layer thickness in the range of 2 μm to 100 μm to thereby ensure existence of a constant gap between the electroluminescence device and the color filter, to prevent color dislocation and to reduce the angle of visibility.
Claim 8
Dependent Claim
36 words
The color film electroluminescence panel of claim 1, wherein the buffer means has a layer thickness of 5 μm to 10 μm to reduce the possibility of color dislocation and to reduce the angle of visibility.
Claim 9
Dependent Claim
44 words
The color film electroluminescence panel of claim 2, wherein the buffer means includes a resin layer, which has a constant layer thickness of 5 μm to 10 μm to thereby ensure existence of a constant gap between the electroluminescence device and the color filter.
Claim 10
Dependent Claim
44 words
The color film electroluminescence panel of claim 3, wherein the buffer means includes a resin layer, which has a constant layer thickness of 5 μm to 10 μm to thereby ensure existence of a constant gap between the electroluminescence device and the color filter.
Claim 11
Dependent Claim
26 words
The color film electroluminescence panel of claim 7, wherein the buffer means has a hardness of zero according to Standard A of the Japanese Industrial Standards.
